Cermet elements are available in a wide range of resistive values. They offer essentially infinite resolution and Literature No. 1773174 Issued: 07-05 excellent stability in most severe environmental conditions. Static and Dynamic noise (CRV) performance is good but does not match that of conductive plastic. Dimensions are shown for reference purposes only. The temperature coefficient of cermet elements, though not as low as for wirewound elements, is better than conductive plastic type elements. Frequency response of cermet Dimensions are in millimetres unless otherwise specified.
